SRW168 Bearing Product Overview & Core Advantages
The SRW168 is a precision single row deep groove ball bearing designed for demanding applications requiring high reliability and consistent performance. Manufactured entirely from stainless steel, it offers excellent corrosion resistance. Its open design allows for versatile lubrication options, while the extended inner ring facilitates easier mounting and axial location. This bearing is engineered to primarily handle radial loads efficiently and is suitable for a wide operating temperature range, making it an ideal choice for compact, high-speed mechanisms.
SRW168 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SRW168 | The base model number, defining the core bearing dimensions and series. |
| Open (Seal Type) | No integral seals or shields, allowing for custom lubrication schemes and higher potential speeds in clean environments. |
| Extended Inner Ring | The inner ring protrudes beyond the outer ring, simplifying axial positioning and locking. |
SRW168 Bearing Structural Features & Performance Benefits
- High-Speed Capability: The open construction, combined with a stainless steel cage and 11 precision balls, enables a high limiting speed of 43,200 rpm, making it an excellent high-speed bearing.
- Corrosion Resistance: All components, including rings, balls, and cage, are made from stainless steel, ensuring long-term performance in humid or corrosive environments.
- Precision & Rigidity: Manufactured to ABEC1 tolerance class with a controlled radial internal clearance (MC3), providing smooth operation and reliable rotational accuracy.
- Robust Load Capacity: Engineered to handle significant radial dynamic loads (64 lbf) and static loads (28 lbf) for its compact size.
- Wide Temperature Range: Operates effectively from -86 to 230 °F, suitable for various industrial conditions.
